Research on key techniques for construction of oblique tied arch of inland waterway bridges
This paper proposes a practical and feasible construction technology plan for the Kunlun Bridge project,taking into account the special requirements of construction technology for inland waterway bridges.The paper first analyzes the characteristics of bridge construction in inland waterways,including limited factors such as narrow construction sites and frequent ship traffic.Afterwards,a detailed discussion was conducted on the overview and main technical difficulties of the Kunlun Bridge project,including linear control of steel bridges and lifting construction of steel beam arches.On this basis,specific measures and key construction technologies were proposed to solve the difficulties,such as overall lifting of large sections and precision control measures for beam assembly.Through the case study of Kunlun Bridge,the construction plan proposed in this article can provide reference for similar projects.
